[Bug c++/21135] New: &a[-2] ICE at the top level

["mrs at apple dot com" <gcc-bugzilla at gcc dot gnu dot org>]

int a[4] = {0,1,2,3};
int *b = &a[-2];

doesn't work, it fails with:

t2.ii:1: internal compiler error: Bus error
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

This ICEes because it is going deep into expand, and there is no cfun, and no insns at that time.

This should be host/target/build independent.
